Unique-Bargains PTFE Tubing 2mm x 4mm 1m Transparent

SKU CH-AKPJ-VEY4N

PTFE tubing with 2 mm inner and 4 mm outer diameter, rated from -70 °C to 200 °C and supplied as a 1 m length

  • Withstands extreme cold down to -70 °C
  • Handles continuous heat up to 200 °C
  • Resists aqua regia and all organic solvents
  • Low-friction surface prevents material sticking during use
  • One-metre length (3.3 ft) ready to cut

Transparent PTFE tubing for 3D printers

This one-metre length of transparent PTFE tubing has a 2 mm inner diameter and a 4 mm outer diameter. It is supplied new and weighs approximately 20 g. The material handles continuous temperatures from -70 °C to +200 °C. It suits RepRap-style printers and other applications needing a low-friction guide path.

Fits Bowden extruders and custom routing

The tubing slides into standard 4 mm push-fit couplers on many Bowden extruders and hot-end assemblies. Its high lubricity reduces filament drag during retraction and long travel moves. The transparent wall lets you confirm filament position visually. It requires no special tools to cut or install.

One metre covers most single-extruder builds

A single 1 m length (3.3 ft) is sufficient for typical Bowden runs on cartesian or CoreXY machines. Multi-extruder setups or very large frames may need additional lengths joined with couplers. The PTFE withstands chemical exposure and retains its dimensions across the full rated temperature range.

Questions about this item

How long can the PTFE tubing handle continuous exposure at its 200 °C upper working temperature?

The tubing is rated for a working temperature range of -70 °C to +200 °C, so it will withstand sustained use at the upper limit without degrading.

Does the PTFE tubing become brittle or emit fumes when run at high temperature all day?

PTFE offers good resistance to high and low temperatures and excellent resistance to organic solvents, so it remains stable and non-stick during extended high-temperature operation.

What inner diameter must my 3D printer's hot-end or bowden coupler accept for this 2 mm ID tubing to fit?

This tubing has an inner diameter of 2 mm (0.078 in) and an outer diameter of 4 mm (0.158 in), so your hot-end or coupler must accommodate a 4 mm OD tube.
